Rear Brake Load Sensing Valve Linkage - ceased

Martin, and others
I've had a look under the car for mine and seen the relevant bit pictured in
the Haynes Manual, but I've also seen another bit that has two springs
either side - I don't know what this brake mechanism is? any ideas Roman?,
Julian?, Clive?, Malcolm? It looks a bit like the picture on 9-16 section
(13.6), called an "equaliser?" - I sprayed both with WD40. If the item is
an 'equaliser' its well-rusted...
Novices don't have much idea and I fall into that bracket...

Hi,
I just purchased a KZJ70 that failed its MOT due to the brake linkage has
seized and the LSPV was leaking around the valve.
Maybe that's why it failed?
Mine needed new linkage and an LSPV to get it through the MOT.

Hi Renate,
First off I am like you a novice and I could be wrong :)
I think that is the handbrake equaliser for balancing out equal tension to
the brakes when you pull the handbrake.
Unfortunately I don't have the Haynes manual in question either, so I cannot
confirm, you should see a cable going to both wheels on the rear axle
attached to the springs if is the hand brake equaliser?

Hi Martin
Nobody is as novice as me...
I guess that is what it is then - makes logical sense, even to my untrained
eye.
It was probably not the best thing to WD40 it...but its so rusted anyway I'm
surprised the hand brake actually works...I tugged it and there's no play at
all - should there be?
I reckon the other bit I saw was the bit thats ceased - however it doesn't
look particularly rusted/corroded to me. Still investigating whether this
is the bit that the mechanic was talking about.
Will oil it again tomorrow and have someone press hard down on the brake
pedal, at least five times (almost like 5 emergency stops equivalent) and
see whether anything (i.e. cable) moves a bit. If it does then its been
unceased...

Sorry but no Renate, the operation of the brake pedal has no effect
on the handbrake. I am sure the brakes work OK but the pedal will
override the handbrake mechanism and leave it where it is - seized
! Its an old problem for those of you that have an auto as you
rarely use it, preferring the 'park' position.
So you have get down and dirty and free it off, and unfortunately if
you can't budge it, or it moves but does not obey the return springs,
then a new cable is needed. Your man's comments about the lever
having little travel or similar, refers to the adjustment of the
cable length which is done by a couple of 10mm nuts on the threaded
end of the cable under the handbrake lever. But that adjustment will
not affect the efficiency of the handbrake. In fact one of your men
may have tried that adjustment - cos its an easy one - to try and
make the handbrake more effective. But still not an alternative to
freeing off the whole linkage and also getting the clevis at each end
of the cable moving away from and to the brake backplate. If you
look, there is a reasonable description on Lcool.
Its time an eligible single girl like you found a 4X4 man for R&R and
then all your problems will be solved ;o)

Its not the cable its the mechanism that's seized (sorry, forgot how to
spell 'seized'for a moment there!)the valve linkage, everything else works
reasonably okay.
When I spoke to toyo parts at the toyo garage it was said that the repair
kit wouldn't be much use at all - so why sell it in the first place then? I
asked myself (seems logical not to sell something that isn't much use...), -
or maybe its just too 'fussy' for them and time consuming, and they'd much
rather sell me a complete (more expensive) part - guess this is why?.
Yeah tis true I'm single but I'm not in the marketplace for a R&R 4x4
mechanic (miracle, if there is ever one! - don't believe in miracles,
dontcha know)
..any takers?...(joke)

Well, you could ask Benoit if his handy mate is free ;o)
Sorry to have been confused on your handbrake cable/LSPV description.
I think most of us regulars would do the seals cos our labour is
free. To get a mechanic to do it at his rate then the replacement
part will no doubt be cheaper. That is if his diagnosis is correct in
the first place as Julian wonders.
Best of luck.
